and arms; and it consists in the manner of forming the joints andsecuring the requisite friction thereto. l

1n the accompanying drawing, Figure 1 represents a doll-body with thejoints constructed according to rnyinvention. Fig. 2 is a leg detached,giving a front view of the joint. Fig. 3 represents the mode ofconnecting the arms with the shoulders. Fig. 4 is an end view of thearm-pivot.

Similar letters of reference indicate corresponding parts.

In the manufacture of dolls it is important to secure sufficientfriction at the joints of the limbs to hold the limbs and body in anydesired position, so that the doll may stand erect or in an inclinedposition, or be supported on its head by the arms.

This friction I obtain by means of a slot, A, and tenon B, fastenedtogether by the pivotpin O. The tenon B is divided by a saw-kerf, D. Thedouble tenon is designed to fit the slot a little full, and the doubletenon be sprun g together slightly, when the tenon enters the slot, thusproducing the requisite friction, and preventing anyvbinding orlooseness by the shrinking and swelling of the wood at any time. slit atright angles, as seen in Fig. 4, and fitted into a round`socket, G,having a groove, F, to receive a pin, so that the arm will be securelyheld, while it Willfre'ely revolve. The socket is a little smaller atthe back end, so that the shoulder-piece is compressed, as represented,which secures at this point the required degrec of friction.4 The arm isattached to the shoulderpiece in the manner already described.

The tendency of the two parts of the tenon to spread when compressed inthe slot is constant, and compensates for wear, and affords thenecessary friction.

Having thus described my invention, I clailn as new and desire to secureby Letters Patent- A dolljoint constructed and formed substantially asshown and described-that is,

with the slot A and teuon B, the latter having the saw-kerf D, as setforth.
